'Be it known` that I, FREDERICK I`IIoMAs, a citizen ofthe United States, residing at y, Philadelphia, in the {county} ofPhiladelphia and State ofi/ Pennsylvaniafhave invented a new and useful Improvement in Creasng Machines, of Whichlthe following "lll ' ticularly at the corners.y Other objects of is a specification.

- The principal object of the present in-A vention is to continethe creasing operation to the edges or margins of the articles, such as knttedpatch pocketsfor sweaters,where by the other portions of the pockets or other articles are not pressed or otherwise marred. Another object -of the inventio-n isM to improve the operation of the dies which clothe creasing so. thatthelatter is improved, parthe invention will appear fromthe following kdescription at the. end of which inven-` tion will be claimed, but the invention .will` `,be rst described in ,connection with the yembodin'ients for the sake ofiillustration in embodiment of itchosen from among other.

the accompanying; drawings forming kpart hereof and in which- K Figure 1 is a side view of a machine embodying features of the invention. y

Fig. 2 is an end view of thesame with parts removed.

Fig.3 is' a top or plan view drawn to an enlarged scale with parts removed. Figa!!L is a transverse sectional View ofthe top ortable of the machine. h

Figs. 5, 6 and 7 are Views illustrative of the operation of themachine,for, more ac-k curately, of a creased product, and

F ig. 8 is a sectional View of a` creased f Y n lles the traveler 16 and ways-16a. There are product. l. i l

In the drawings lis-a holding plate or foot contoured for the outline of the folded article. This footo-r plate 1' is shown as carried by a manually operated arm 2 pivoted at 3'to a bracket L1 mounted on the table central space generally indicated at 9, for

the accommodation of the bodyfof Lthe fabric to protect it from being pressed during the operation of creasing its edges. `As

`shown the frame detachablyv rests upon the ytop ofthetab'le a and isheld against .accidental movementy by means of .stays 10 having detachableconnection .withv pinsll projecting. upward from the table a. The described construction isv such that anyy frame canbe readily replaced by another. The I margin of the frame is shownas beveled? andk this facilitatesthe initial folding orv start of the creasing of they fabric when the foot or plate 1 is`depressed on top ofthe fabric. Dies 12and 13 are employed and i the number of dies is not important and may be increased or diminished depending upon the shape ofthe article to be creased. -As

shownthere',are'three dies and a die blank is shown at 14g.` 15 and 16 are travelers slidable 1n generally radially arranged waysr 16a and provided with lips17 spaced abovethe top of the table a. yThe shanks of the dies underlie these lipsfand are provided with pins which lproject upwardly asat 18 and `detachably1 engage holes in the lips 17so thatltlie travelers may be lifted to cleartheA pins and in 'that vwayy the dies can -be readily changed-- 'These` pinsproject vdownwardly 'as at 18a and slide upon the table a. In this descriptionv reference will be made to creas- 111g a pocket because the machine shoWn is arranged flor ythat purpose' but of course the yinvention is not limited to creasing-pockets. The dies 12` are provided with wings -19 that Work in spaces provided underneath the die 13. The notches 21 are of structuralr advantage in forming the spaces 20., 22 is a ring turntable by means of the handle 23 and guided by guides 24 of which one co-operates with a stop 25 on the ring.

and with the handle, 23. The ring22 over.-

links interposed between the ring 22 and the travelers *and some 26 of these links extend toward the center of the ring, and some 27 extend awayfrom the center ofthe ring to progressively shift the dies toward the center; In the present instance, the dies 12 will approach the center in advance of.,V

yshown onk the drawings, andthe heads 3()y a of these rods overlie the lips17and the -shanks ofthesefrods work in notches 31 in the die 13,` and of course of the` die blank "i 14, lit being assumed that the ring 22 is Beneath the vtable there y the dies so that when the frame isdrawn" dovvn, the dies rare pressed down and thel toward the left in Fig. l, the toggle levers are straightened and the dies are pressed dovvn onto the frame, the parts 37 serving as a stop. 42 isa treadle by means of which 'the toggle levers are thrown out of line and into the position shown in Fig. l. ln creas ing an article, tor example,`a knitted pocket I) along the dotted lines shown in Fig. 5,

Vthe fabric is put onto the frame with its bottom and side edges arranged over the margins 7. rllhe foot or plate l is then turned down and its rim holds'the fabric to the margins 7 slightly turning up the bottom and side edges of the fabric. rlhe ring Q2 is then turned With the result that the dies l2 are pushed inward turning down and over-riding` the side edges ot the fab- Yric, as shown in Fig. (5. Then the die 13 movin@` inward, turns down the bottom edge of the fabric as shown in Fig. 7. The pedal -llis then pushed inward with the result that the dies press down and crease the edges only o'lE the fabric and it is important that the renter portion of the fabric occnpy ing the space 9 is not pressed and its inish is not marred or spoiled Which is always iniportant but particularly important in connection with thick sott knit goods. yThe fact that the pressing is confined to the edges is intended to be illustrated in Fig. S. Heat may be and usually is applied during the creasing operation and upon the tompletion of the latter the treadle 4Q is operated and the ring and arm 2 restored to their original positions. v

I claim:

l. In a creasing machine the combination of a holding :toot or plate contoured for the outline of the article to be creased, a` frame having a margin contoured for cooperation with the rim of the plate or foot to receive the edge portion of the fabric therebetween and having central space for the accommodation of the body of the fabric to protect it from being pressed, dies for 1 creasing the edge portions of the fabric, means for shifting the dies toward the center of the toot or plate and over the top thereof, and devices for` pressing the die; toward the plate or foot.

2. lin a creasing machine the combination ot a holding foot or plate, dies cooperating ivith said plate to crease the edges ol the fabric held by the plate, a turnable l a 1 ring tor radially shitting the dies, and links 'interposed between the ring and dies and ot which some extend outside and some inside ot' the ring to progressively shift the diesk tentrally.
